Application filed June. 2, 1919. SeriaINo. 301,222. j

and State of Indiana, have invented a certain new and useful Lamp-Door Construction; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like nuv merals refer to like parts.

*This invention relates to the construction v of the rim for a headlight *door orlamp so as to give it the appearance of a solid and massive metal rim,-'whereas 1n fact 1t is formed entirely from a stamping process of sheet metal. 'This is accomplished by means of stamping out two shells, embodying one stamping operation each, mounting them together, and joining them to form a single rim.

Referring to the drawings, which are made a part of this application, Figure 1 is a front elevation of the lamp door. 2 is a side elevation with the {upper portion shown in section. Fig. 3 shows'a section through the stamping of the outer shell. Fig. 4 shows a section through the stamping of the innerfshell. LFig. 5shows a. sectionthrough the two. stampings form the door rim.

In the drawing there is shown a lamp door rim'having an outer octagonal shell 10 assembled to with an inner circular bead ll-formed therein adie which draws the wall 13 upwardly,

Specification of Letters Patent; I Patentd Feb. 22 192 1 Y its periphery being. circular and provided: V

with a lateral flange 14, which has its periphery octagonal so as to correspond to the octagonal shapeformed in the wall- 12.

The inner portion of said inner shell *is stamped in the same operation to provide a laterally extendingfrim 16, with a down wardly projecting flange 17, and with a plurality of ears l8 sheared from the rim 16 and turned upwardly to form a supporting and retaining means for the lens to be I secured in said door.

Before assembling the shells the inner shell has a-re'cess 19 stamped out-whereby said lamp door may be mounted and secured to the casingby Ineansof hooks extending therethrough.

' After the shells have-been stamped andformed they are assembled as shown in F 1gs.' 2 and 5, belng'fsecured'together by a spot welding process at intervals 20 to'the inner, rim, and soldered atfth'e joint '21 to the inner periphery? I s The invention claimedis:

A sheet metal door-for lamps havingwa circular inner rim 'and'a'non circularouter periphery, consisting of anlouter member having the-wall thereofof' anon-circular shape, an inner shell havingthe wall thereportion of non-circular shape to coincide of'of circular shape and having a lateral whereby the edgesthereof mayregisterwithl' each other, meansxfor securing the-edges of" said shell together whereby the sheet metal I doorcomprised of two shells will give the" so 1 appearance of a solid non-circular shaped door rim, and means integral with the in ner shell for; securing"a"closure member within the outer shell.

In witness whereof, I have hereunto a fixed my signature.
